Empirical Validation of Large-Angle and Long-Distance Helicopter Training Scenarios

The flight simulator industry plays a crucial role in high-intensity pilot training, offering economic benefits, reusability, and enhanced safety features. Historically, most motion platforms for such simulators have utilized Stewart platforms, yet their parallel mechanism design is not effectively suited for long-stroke motion simulation. Therefore, the rotor-based simulator designed in this paper possesses characteristics of linear forward movement and continuous rolling, allowing rapid and flexible adjustments in flight direction, altitude, and position to meet various mission requirements. Firstly, to enhance the simulated sensations, each axis is independently designed to improve the overall motion range. Secondly, the relationships between each axis are derived from kinematics theory and motion platform transformation. Subsequently, through the use of DSP, TMS-320F-28377D, embedded motion-cueing algorithms are designed, along with the development of rotorcraft flight software, and integration of the platform control cabinet utilizing network communication and digital communication technology to enhance control safety and data transmission stability of large-scale motion platforms. This enables pilots to truly immerse themselves in large-angle and long-distance training scenarios. Finally, a measurement system is established to monitor parameters including attitude, velocity, and acceleration, implementing nine training themes, with empirical results verifying the practicality and feasibility of the system.
